To all whom it may concern.-

Be it known that I, LUCENA M. MORDEN, a citizen of the United States,and a resident of Portland, county of Multnomah, and State of Oregon,have invented certain new and useful Improvements in Separate-LeafBooks,

of which the following is a specification, ref-, erence being had to theaccompanying draw ings as a part hereof.

My invention relates to blank books of the vented an improvement inblank books of this character, for which invention I made applicationfor Letters Patent of the United States, filed June 24, 1898, Serial No.684,438;

and the object of my present invention is the further perfection of suchblank books, so as to .make them well adapted for convenient use.

The binding or filing rings of my present invention are of betterconstruction for the purpose intended, and the-outer covers are sojoined together as to be more easily handled and adjusted and at thesame time presentinganeaterappearance. These features of mypresentinvention will be apparent from the said drawings, in whichFigure 1 is a perspective of my invention. Fig. 2 is a side elevation ofthe same. Fig. 3 is a plan of one of my file or hinder rings. Fig.4 is'apartial plan of the base of my book, showing the upper edge providedwith slots, a knuckle, and a pair of binder-rings hinged in such slots;and Fig. 5 is an elevation of one of my binder-rings, with parts brokenaway to show those portions of such ring which are of specialconstruction.

The lettersdesignate the parts referred to in the description of myinvention.

The fundamental plan of construction of my book is like that of my priorinvention. A number of single sheets ofpaper are removably bound betweentwo outer covers by means allowing the paper to be so arranged as to lieflat in every position convenient for writing. In my present inventionthe outer covers, the binding-rings, and the arrangement of the frontcover are better adapted to their work. The base or under cover a hasare hinged in place, the pintle passing through an eye e in the base ofeach ring. This contrivance'enables the rings to accommodate themselvesto the arrangement of the paper. The construction of the rings is shownin Fig. 5, being made of two pieces or members (1 (1 The U-shaped lowerpart comprises two straight parallel arms and an arched base, and thehead (i is a locking-bar similarly arched as the base of the member d towhich it is pivotally attached. The extremity of the left arm of themember d has a socket d, and the corresponding end of the bow d adependent pintle (1 inserted in such socket. The middle portion of suchpintle is reduced, so as to form a peripheral groove (i and the wall ofsaid socket opposite to said groove is slightly dented to form a stud dprojecting into said groove and retaining the pintle in place. The

free end of the locking-bar is concaved to form a vertical groove f, thelateral extremities f e of which form small jaws embracing the extremityof the right arm of the body of the ring and by so doing lock thecontacting ends when the bar is closed. The extremity d is rounded tofacilitate the passing of the paper over the rings. When opening thering, the locking end of the bar is sprung out of its engagement withthe contacting arm. The

shape given to my rings in the drawings is merely adopted as calculatedto give the greatest convenience and freedom of use. I do not, however,limit myself to any particular shape.

The base or under cover and the upper cover are joined by meansconstituting one of the important features'of my invention. The base ais made of inflexible material. The upper cover g is made in part ofinflexible material, joined to which is a flexible binding-strip it,being, in fact, an extension of the upper cover to about the length ofthe base, and the base and upper cover are joined by means of a flexibleback strip i, one end of which is secured to the binding edge of thebase away from the knuckle, so as not to in' j of which has a socket; alocking-bar having a pintle journaled in such socket; a groove 7 apintle jou-rnaled in such socket; a groove terfere with the movement ofthe bindingrings, and theother end of such binding-strip being attachedto the upper cover at h, the place of union between the inflexible coverg and. the flexible binding-strip h. The function of the flexiblebinding-strip h is to hold the cover 9 in place without interfering withany convenient arrangement of the leaves. The flexible cover h isperforated atits binding edge, so as to be engaged by the bindingrings.All this is illustrated in Fig. 2, where a section .of the leaves isshown turned under the base, and the relation and operation f of all theparts of my invention are illustrated in Fig. 1. x

Now what I claim, and desire to secure by Letters Patent,is--

1. A binding or file ring composed of two members, one of whichcomprises 7 two branches united'in an arched base and the other being alocking-bar, the extremity of one of said branches having a socket, (Zand the corresponding end of the locking-bar a dependent pintle which isjourna'led in such socket, and means for retaining the pintle in place,the outer or free end of suchlockingbar and the extremity of thecorresponding branch being adapted to look when brought in contact witheach other upon the closing of the ring. I i 2. A binding or'file ring,comprisingan approximatelyU-sh'aped body, one of the arms on theperiphery of the pintle; a stud dented in the wall of the socket andentering such groove; and the contacting ends of the lockinghar and ofthe body being adapted to lock when the bar is closed.

3. A binding or file ring, comprising an approximately uv-shaped body,one of the arms of which has a socket, a locking-bar having on theperiphery of the pintle; astud dented in the wall of the socket andentering such groove; the free end of the locking-bar ha-v-j ing avertical groove, the extremities of which constitute jaws engaging thecontacting extremity of the body when said parts are brought in contactwith each other. 4. A blank book, comprising in combination, aninflexible base or under cover; an

inflexible upper cover of lesser length than the base; a flexiblebinding-strip as h, suitably perforated and inserted on thebindingrings, such strip being an extension of said upper cover to aboutthe length of the base;

a slot in the binding edge of the base; a

knuckle attached to such edge and correspondingly slotted; a file orbinding ring hinged in such slot, and having an opening portion, thefree end of which, and the contacting end of the body of the ring, areadapted to look when brought in contact with each other upon closing thering; and a number of loose sheets of paper, the binding edges of whichare suitably perforated and inserted on such binding-ring.

5. In a blank book, of the class specified, an inflexible base or undercover; an inflexible upper cover of lesser length than the base; aflexible binding-strip, as h, beingan extension of the upper cover toabout the length of the base; and a flexible back strip joining the baseand the upper cover, substantially as described.

6. A blank book, comprising in combination, an inflexible base or undercover; an inflexible upper cover of lesser length than the base; aflexible binding-strip as h, suitably perforated and inserted on thebindingrings, such strip being an extension of the upper cover to aboutthe length of the base; a flexible back strip joining the base and theupper cover, such back strip being attached said binding-strip; a slotin the binding edge of'the base; a knuckle attached to such edge andcorrespondingly slot-ted; a file or binding ring hinged in such slot,and having an open-' ing portion, the free end of which, and thecontacting end of the body of the ring are adapted to look when broughtin contact with each other upon closing the ring; and a numberof loosesheets of paper, the binding edges of which are suitably perforated andinserted on such binding-ring.
